PORTLAND, Maine — A Maine man is teaching people how to grow medical marijuana at what’s being called “Marijuana State University.”

Fifty-six-year-old Ray Logan has been growing marijuana for 30 years, but when he started it was a recreational and illegal hobby. Now he’s taking advantage of Maine’s medical marijuana law to share his expertise legally.

He taught his first class earlier this month in Portland. More classes are scheduled.

The Portland Press Herald says Logan is offering three-hour workshops for people who want to learn how to grow high-quality marijuana in their homes.
